WILLIAM GENTRY SHELTON, OF NEW YORK, N. Y.

Application filed May 14,

To all 1071 omit may concern Be it known that I. IVILLIAM GENTRYSin-itxrox, a citizen of the United States of America, residing in theborough of Manhattan. city. county. and State of New York, have inventedcertain new and useful Improvements in Power-Driven Implements forCutting Hair or the like, of which the following is a specification. I

This invention relates to improvements in power-driven clippers orimplements for cutting hair or the like, and aims to provideimprovements therein.

The present invention provides a' powerdriven clipper, wherein theelectric motor for supplying the power is associated with the handle andcutter parts, and wherein the arrangement is such that the heat of themotoris not objectionably communicated to the hand of the user of theimplement.

The invention further provides a simple and economically producedimplement of the character described. Other features of improvement willbe hereinafter set forth.

An embodiment of the invention is illustrated in the accompanyingdrawings, where- 1n Figure 1 is a longitudinal sectional view of saidembodiment.

Fig. 2 is a front elevation, and 1 Fig. 3 is a cross sectionon the lineIII-III, Fig. 1.

In said drawings, numerall designates the cutter mechanism, 2 the motorand 3 the handle. The cutter preferably comprises blades 4 and 5, one ofwhich, as for example the blade 4, is reciprocated over the other. 6designates a two-armed oscillatory lever, driven by the motor 2 througha reduction transmission or gearing 7 The axis 8 of the motor ispreferably substantially parallel to the axis 9 of the oscillatory lever6, and has on said axis, con nected to the'driving shaft of the motor, aworm 10. In connection with the worm 10 is a gear 11. -The gear 11 ismounted upon a pin 12, the axis of which is'radial to the axis 9 of thecutter. The gear 11 has a crank pin 14 thereon, and the lever 6 has aslotted or bifurcated portion 15, in which the pin 14 works. The pin 14preferably has thereon a ball 17 and the contiguous 1919. Serial No.297,083.

walls of the slotted portion 15 and the lever 6 have a correspondingcontour, as indicated at 18. ,The contiguous faces of the gear 11 andportion 15 of the lever 6 are preferably respectively spherically convexand concave.

The motor 2 and the cutter are preferably enclosed within a singlecasing 20, comprising the parts 21 and 22, the bottom cutter 5 beingsecured to said casing, and the upper cutter being partially covered andpressed upon by a spring pressed cover plate 23.

21 is a switch device whereby the motor may be conveniently started andstopped.

The handle 3 is preferably attached to the casing at an angle to theaxes 8 and 9, the angular isposition corresponding to the levers uponhand-actuated clippers, now generally used, as for example the Brown andSharpe clipper.

The handle 3 is conveniently provided with a passage 26 for the leadingin Wires to the electric motor. i

The arrangement of the handle and motor casing permits of the motorbeing made suiticiently large in size to develop the driving forcerequired, andtoavoid excessive heating, and the handle is not subject tothe direct heating effects of the motor, so that it may be grasped andused with comfort.

The invention may receive other mechanical expressions than that hereinspecifically illustrated and described.

lVhat is claimed is: Y

1. An implement for hair-cutting comprising a motor, a cutting tool, anoscillatory tool-actuating lever and a worm and gear transmissionbetween said motor and lever, said motor and lever turning onsubstantially parallel axes, said gear turning on an axis radial to theaxis of said lever, and said lever having one end bent upward to aposition substantially parallel with the axis of said motor, wherebysaid motor may be located substantially above the heel of said cuttingtool.

2. An implement for hair-cutting comprising a motor, a cutting tool, anoscillatory tool-actuating lever and a Worm and gear transmissionbetween said motor and lever, said motor and 'lever turning onsubstantially parallel axes, said gear turning on an axis radial to theaxis of said lever, and 3. An implement according to claim 1, saidlever'having one end bent upwardly and further characterized by saidgear having a laterally to a position substantially parallel crank pinthereon coacting with the up- 10 with and to one side of the axis ofsaidwardly bent end of said lever. 5 motor, whereby said motor may belocated In Witness whereofilhave hereunto signed substantially above theheel of said cutting my name.
